For me, it's a sad but not shocking news. We could see it coming for some time. Plasma television sales have been on decline for some years now. Other manufacturers have already exited plasma TV segment. However, I don't think, Panasonic will exit plasma TV segment in 2013 itself. Plasma TV technology leadership is what separates them from the competetors. I don't think, they can really compete with South Korean manufacturers in LED LCD TV segment. My guess is, Panasonic and others will ultimately exit the Plasma TV segment but not so soon. I think, manufactureres will consolidate number of plasma TV models on offer in 2013 and we may see new (fewer) plasma TV models in 2013 from Panasonic, Samsung and LG as well. Just my guess and hope. I'm no expert on this subject.
I think, we may not see plasma TVs from any manufacturer in 2015. I'm not sure how Panasonic is in terms of customer service and supporting their products. Do they stand firmly behind their products and customers? I'm asking because as customers we need assurance that the company will provide support even if they discontinue the product, before we buy the product from the company. I think, if someone wants to buy a plasma TV now, s/he should buy it from a manufacturer who has a reputation of good customer service and who stands firmly behind the products they manufacture.
